Please ask the retailer from whom the watch was purchased for replacement of the secondary battery. Installation of an ordinary silver oxide battery can generate heat that can cause bursting and ignition. 2 READ FIRST ASTRON 8X82 GPS SOLAR CONTENTS 1 CAUTIONS WARNING Do not use the watch in scuba diving or saturation diving. Do not turn or pull out the crown when the watch is wet. The various tightened inspections under simulated harsh environment, which are usually required for watches designed for scuba diving or saturation diving, have not been conducted on the water-resistant watch with the BAR (barometric pressure) display. For diving, use special watches for diving. Water may get inside of the watch. If the inner surface of the glass is clouded with condensation or water droplets appear inside of the watch for a long time, the water resistant performance of the watch is deteriorated. Immediately consult the retailer from whom the watch was purchased or SEIKO WORLDWIDE SERVICE NETWORK. Do not leave moisture, sweat and dirt on the watch for a long time. CAUTIONS Be aware of a risk that a water resistant watch may lessen its water resistant performance because of deterioration of the adhesive on the glass or gasket, or the development of rust on stainless steel. Do not pour running water directly from faucet. The water pressure of tap water from a faucet is high enough to degrade the water resistant performance of a water resistant watch for everyday life. Do not wear the watch while taking a bath or a sauna. Steam, soap or some components of a hot spring may accelerate the deterioration of water resistant performance of the watch. 3 READ FIRST ASTRON 8X82 GPS SOLAR CONTENTS 1 Features This is a GPS solar watch. GPS is an abbreviation for Global Positioning System. For details, see P. 5 This watch has the following features. GPS signal reception Solar charging Function This watch can be set to the precise local time by just one button operation anywhere in the world. DST (Daylight Saving Time) can be set manually. This watch quickly adjusts the time by receiving GPS signals from GPS satellites. Place where GPS signals can be easily received/ cannot be received P. 15 This watch responds to a total of 40 time zones around the world Time Zone P. 6 When the region or time zone where the watch is used is changed, please carry out operation of “time zone adjustment.” How to adjust the time zone P. 17 This watch operates by solar charging. Expose the dial to light to charge the watch. Once fully charged, the watch runs for approximately 6 months. When the energy stored in the watch runs out completely, it takes time to fully charge the watch, so please keep in mind to charge the watch regularly. How to charge the watch P. 13 Standard charging time P. 13 Automatic time adjustment function This watch automatically adjusts the time in accordance with action patterns during use. When the watch has sensed sufficient brightness under an open sky, it automatically receives GPS signals from GPS satellites. This function enables the watch to automatically adjust the time precisely even while you are using the watch. Automatic time adjustment P. 24 This watch is unable to receive GPS signals when the energy stored in the watch is low. Check the Charging Status P. 12 Unlike navigation equipment, this GPS solar watch is not designed to constantly receive GPS signals from GPS satellites without any operation. This watch receives GPS signals only in the time zone adjustment mode, automatic or manual time adjustment mode. 4 READ FIRST ASTRON 8X82 GPS SOLAR CONTENTS 1 Mechanism by which the GPS solar watch sets time and date What GPS is GPS stands for Global Positioning System, a satellite positioning system for determining the current position on the earth. 24 satellites cover the earth, and at present, the system is operated by approximately 30 GPS satellites. Wherever you are in the world, the position can be determined (positioned) by information from more than 4 GPS satellites. GPS satellite This is a satellite operated by the United States Department of Defense (official name is NAVSTAR), and orbits the earth at an altitude of 20,000 km. Initially, this was a military satellite, but at present, information is partially disclosed to the public and used in various equipment including car navigation systems and cellular phones. The GPS satellite is mounted with a high-accuracy atomic clock with an accuracy deviation of 1 second per 100,000 years. 5 Mechanism by which this watch sets the time and date This watch receives GPS signals from GPS satellites to set the time and date based on the following information. •Precise time and date based on the atomic clock •Information about a time zone where you are (The current location is basically positioned by more than 4 GPS satellites, and which zone of the total of 40 time zones around the world you are in is identified.) To receive information about a time zone where you are, it is necessary to adjust the time zone. How to adjust the time zone P. 17 Unlike navigation equipment, this GPS solar watch is not designed to constantly receive GPS signals from GPS satellites without any operation. This watch receives GPS signals from GPS satellites only in the time zone adjustment mode, automatic or manual time adjustment mode.

BEFORE USE ASTRON 8X82 GPS SOLAR CONTENTS 3 About charging How to charge the watch Standard Charging Time For an approximate time required to charge the watch, refer to the table below. Expose the dial to light to charge the watch. GPS signal reception consumes a lot of energy. Keep in mind to charge the watch by expose to light so that the indicator hand points to the “level position (middle)” or “F (full).” (If the charging status is displayed as “E (low),” the reception will not start even with operation of GPS signal reception.) Check the charging status. P.12 To ensure optimal performance of the watch, make sure that the watch is kept sufficiently charged at all time. Illumination lx (LUX) Under the following situations, the energy of the watch is likely to be depleted, resulting in stoppage of the watch. 700 •The watch is concealed under a sleeve. •The watch is used or stored under conditions where it cannot be exposed to light for a long time. When charging the watch, make sure that the watch is not heated to a high temperature. (The operational temperature range is between –10 °C and +60 °C.) When first using the watch or starting to use the watch after it has stopped because of the energy depletion, sufficiently charge the watch referring to the table on the page at the right. Light source Condition (Example) Fluorescent light General offices 3,000 Fluorescent light 10,000 Fluorescent light Sunlight 100,000 Sunlight 30W 20cm Cloudy day 30W 5 cm Sunny day (Under the direct sunlight on a summer day) From the state where the watch is stopped (not charged) To fully charged To one-second interval movement is secured - - In the state where the hand moves (the watch is charged) To move for one day 3.5 hours 420 hours 12 hours 1 hours 115 hours 4 hours 15 minutes 50 hours 1.5 hours 10 minutes The figures of “Time required for charging the watch to start moving at one-second intervals” are estimations of time required to charge the stopped watch by exposing it to light until it moves at steady one-second intervals. Even if the watch is partially charged for a shorter period, the watch will resume one-second- interval movement. However, it may shortly return to two-second-interval movement. Use the charging time in this column as a rough guide for sufficient charging time. The required charging time slightly varies depending on the design and the dial color of the watch. 13 BASIC OPERATION (HOW TO SET THE TIME/HOW TO RECEIVE GPS SIGNALS, ETC.)

ASTRON 8X82 GPS SOLAR Automatic time adjustment This watch can be set to the precise current time by automatically receiving GPS signals by exposure to bright light outdoors under an open sky to adjust the time. In addition, when the watch is concealed under a sleeve and the dial is not exposed to sufficient light even if outdoors under an open sky, the watch stores the time of the previous successful manual time adjustment (or time zone adjustment), and automatically starts time adjustment at the same time. In a place without good visibility, GPS signals cannot be received. Place where GPS signals can be easily received/Place where GPS signals cannot be received P. 15 If the energy is sufficiently charged, automatic reception will be performed every day. The automatic time adjustment is performed at most once per day. Therefore, even if automatic time adjustment has failed, the next automatic time adjustment will be performed the next day or thereafter. The time zone is not adjusted in the automatic time adjustment. When the region where the watch is used is changed, please carry out time zone adjustment. How to adjust the time zone P. 17 < When it is difficult to expose to light sufficiently > Even if outdoors under an open sky, when the watch is concealed under a sleeve in winter time, etc., in an area where the daylight hours are short, or when the watch is not likely to be exposed to sufficient light for a long time due to bad weather, the watch is designed to allow for automatic time reception at the time when the manual time adjustment was successful the last time. When the watch is exposed to the operating environment above, automatic time adjustment is likely to be successful by making manual time adjustment successful in time periods where the watch is frequently used in a place where GPS signals can be easily received under an open sky. How to manually adjust the time P. 23 However, as the watch judges to start automatic time adjustment taking into consideration the following conditions, the watch does not necessarily start automatic time adjustment by exposure to bright light. •Charging status •Past reception status When the indicator hand points to “E (low),” or in the in-flight mode ( ), automatic time adjustment does not work. When the indicator hand points to “E,” charge the watch by expose to light. How to charge the watch P. 13 Check the charging status P. 12 When the energy is reduced, the period for which automatic time adjustment is not performed becomes longer. Keep in mind to charge the watch regularly. If the time zone adjustment or manual time adjustment is performed before the automatic time adjustment is started, the automatic time adjustment is not performed on that day. When the stopwatch is moving, the automatic time adjustment is not performed. 24 CONTENTS 4 BASIC OPERATION (HOW TO SET THE TIME/HOW TO RECEIVE GPS SIGNALS, ETC.)

Therefore, lack of care may accelerate deterioration of the band or cause skin irritation or stain on the sleeve edge. The watch requires a lot of attention for long usage. ●Metallic band ●Polyurethane band • Moisture, sweat or soil will cause rust even on a stainless steel band if they are left for a long time. • Lack of care may cause a yellowish or gold stain on the lower sleeve edge of shirts. • Wipe off moisture, sweat or soil with a soft cloth as soon as possible • To clean the soil around the joint gaps of the band, wipe it out in water and then brush it off with a soft toothbrush (Protect the watch body from water splashes by wrapping it up in plastic wrap etc.) • Because some titan bracelets use pins made of stainless steel, which has outstanding strength, rust may form in the stainless steel parts. • If rust advances, pins may poke out or drop out, and the watch case may fall off the bracelet, or the clasp may not open. • If a pin is poking out, personal injury may result. In such a case, refrain from using the watch and request repair. ●Leather band • A leather band is susceptible to discoloration and deterioration from moisture, sweat and direct sunlight. • Wipe off moisture and sweat as soon as possible by gently blotting them up with a dry cloth. • Do not expose the watch to direct sunlight for a long time. • Please take care when wearing a watch with light-colored band, as dirt is likely to show up. • Refrain from wearing a leather band watch other than Aqua Free bands while bathing, swimming, and when working with water even if the watch itself is water-resistant enforced for daily use (10-BAR/20-BAR water resistant). 37 • A polyurethane band is susceptible to discoloration from light, and may be deteriorated by solvent or atmospheric humidity. • Especially a translucent, white, or pale colored band easily adsorbs other colors, resulting in color smears or discoloration. • Wash out dirt in water and clean it off with a dry cloth. (Protect the watch body from water splashes by wrapping it up in plastic wrap etc.) • When the band becomes less flexible, have the band replaced with a new one. If you continue to use the band as it is, the band may develop cracks or become brittle over time. ●Silicone band • As for material characteristics, the band is easily dirtied, and may be stained and discolored. Wipe off dirt with a wet cloth or cleaning tissue. • Unlike bands of other materials, cracks may result in the band being cut. Take care not to damage the band with an edged tool. Notes on skin irritation and allergy Skin irritation caused by a band has various reasons such as allergy to metals or leathers, or skin reactions against friction on dust or the band itself. Notes on the length of the band Adjust the band to allow a little clearance with your wrist to ensure proper airflow. When wearing the watch, leave enough room to insert a finger between the band and your wrist.

Lumibrite is a newly-developed luminous paint that absorbs the light energy of the sunlight and lighting apparatus in a short time and stores it to emit light in the dark. For example, if exposed to a light of more than 500 lux for approximately 10 minutes, Lumibrite can emit light for 3 to 5 hours. Please note, however, that, as Lumibrite emits the light it stores, the luminance level of the light decreases gradually over time. The duration of the emitted light may also differ slightly depending on such factors as the brightness of the place where the watch is exposed to light and the distance from the light source to the watch. In general, when you enter a dark place from a bright environment, your eye cannot adapt to the change in light levels quickly. At first, you can hardly see anything, but as time passes, your vision gradually improves.

Unlike an ordinary silver oxide battery, the secondary battery does not require periodic replacement. Overcharge prevention function When the secondary battery is fully charged, the overcharge prevention function is automatically activated to avoid further charging. There is no need to worry about damage caused by overcharging no matter how much the secondary battery is charged in excess of the "time required for fully charging the watch". The capacity or charging efficiency may gradually lower due to long-term use or operating environment. In addition, long-term use may shorten the charge duration due to wear, contamination, lubricant deterioration of mechanical parts, etc. Request repair when the performance lowers. Refer to "Standard charging time" on page 11 to check the time required for fully charging the watch. WARNING Notes on charging the watch WARNING • When charging the watch, do not place the watch in close proximity to an intense light source such as lighting equipment for photography, spotlights or incandescent lights, as the watch may be excessively heated resulting in damage to its internal parts. • When charging the watch by exposure to direct sunlight, avoid places that easily reach high temperatures, such as a car dashboard. • Always keep the watch temperature under 60°C. Notes on replacing the second battery • Do not remove the secondary battery from the watch. Replacement of the secondary battery requires professional knowledge and skill. Please ask the retailer from whom the watch was purchased for replacement of the secondary battery. • Installation of an ordinary silver oxide battery can generate heat that can cause bursting and ignition. When the watch has not been charged for a long time If the watch has not been charged for a long time, the watch will be completely discharged and no longer able to be charged. In this case, consult the retailer from whom the watch was purchased. 40 TO PRESERVE THE QUALITY OF YOUR WATCH ASTRON 8X82 GPS SOLAR CONTENTS 6 After-sale service ●Notes on guarantee and repair ●Inspection and adjustment by disassembly and cleaning (overhaul) • Contact the retailer from whom the watch was purchased or SEIKO WORLWIDE SERVICE NETWORK for repair or overhaul. • Within the guarantee period, present the certificate of guarantee to receive repair services. • Guarantee coverage is provided in the certificate of guarantee.
